Unraveling Twisted Pouch Syndrome: A Narrative Review of Classification, Diagnosis, Treatment, and Prevention.

BACKGROUND: We recently described a cluster of symptoms known as twisted pouch syndrome that rarely affects patients with ileoanal pouches. Herein, we present a narrative review in which we describe the diagnosis, treatment, and prevention of twisted pouch syndrome, with a focus on a simple classification schema. METHODS: Diagnostic signs from endoscopic and radiological examinations, treatment, and prevention strategies are presented. RESULTS: Patients with twisted pouch syndrome suffer from a triad of obstructive symptoms, erratic bowel habits, and pain which may be severe, debilitating visceral pain, all in the setting of a mechanical pouch abnormality. Diagnostic modalities include imaging, careful pouchoscopy, functional testing, diagnostic laparoscopy or laparotomy, and recently 3-dimensional pouchography. Classification of twisted pouch syndrome is based on the location and degree of rotation of the pouch and its mesentery. Outlet twists may result when the distal pouch rotates >90° to 360° clockwise inadvertently during anastomosis; when only the distal most pouch is twisted, it results in an iris-like deformity of the pouch outlet, or when the distal half of the pouch is twisted, a mid-pouch stenosis and an hourglass-shaped pouch may result. Inlet twists are either a full 360° (mesentery posterior), unintentional 180° (mesentery anterior), or 90° counterclockwise twists. Both inlet and outlet twists are fixed deformities and may only be reduced by disconnecting the entire pouch from the anus. If they result in twisted pouch syndrome, a redo pouch procedure or pouch excision is required to reduce the twist; 90° counterclockwise twists may undergo pouch inlet transposition. Adhesive twists result when the pouch becomes fixed in the pelvis in an abnormal configuration, such as when the efferent limb becomes twisted underneath the afferent limb secondary to an occult tip of the J leak, and may be reduced by pelvic adhesiolysis with or without pouch revision. CONCLUSIONS: Pouches may rarely be inadvertently twisted during construction or twisted owing to adhesive disease or leaks. A high index of suspicion is needed to establish the diagnosis. We present a simple classification of twisted pouch syndrome that may aid in the prevention and recognition of these often difficult to diagnose postoperative complications.

In this article, we report a simple classification system for the mechanical pouch complication known as twisted pouch syndrome, including diagnostic signs from endoscopic and radiological examinations, treatment, and prevention strategies.

TOGA Therapeutic Oxygen for Gastrointestinal Atony.

Background and Aims: Ileus, mechanical bowel obstruction, and acute colonic pseudo-obstruction are characterized by distension of the intestines with accumulated bowel gas. Current treatments are not completely satisfactory. Methods: By manipulating the partial pressures of oxygen and nitrogen in the trapped air with a novel 6-hour treatment with 100% oxygen via nonrebreather mask, the bowel can be successfully decompressed, facilitating resolution of the underlying condition. Results: A positive clinical response was seen in 7/8 [87.5%] patients after therapeutic oxygen for gastrointestinal atony. Maximal lumen diameter decreased by an average of 1.14 ± 0.87 cm [16%]. Conclusion: In this first clinical report of therapeutic oxygen for gastrointestinal atony, the provision of 100% oxygen via nonrebreather mask is a useful therapy. It decreased the diameter of the intestinal lumen and enhanced resolution of ileus, acute colonic pseudo-obstruction, and bowel obstruction. This is a low-morbidity, low-cost treatment of gastrointestinal luminal distension.ClinicalTrials.gov Identifier NCT03386136.st.

Outcomes of patients admitted with malignant small bowel obstruction: a subgroup multicentre observational cohort analysis.

INTRODUCTION AND PURPOSE OF THE STUDY: Small bowel obstruction (SBO) accounts for a substantial proportion of emergency surgical admissions. Malignancy is a common cause of obstruction, either due to a primary tumour or intra-abdominal metastases. However, little is known regarding the current treatment or outcomes of patients with malignant SBO. This study aimed to characterise the treatment of malignant SBO and identify areas for potential improvement and compare overall survival of patients with malignant SBO to patients with non-malignant SBO. MATERIALS AND METHODS: This was a subgroup analysis of a multicentre observational study of patients admitted with SBO. Details regarding these patients' diagnoses, treatments, and outcomes up to 1-year after admission were recorded. The primary outcome was overall survival in patients with malignant SBO. RESULTS: A total of 316 patients with small bowel obstruction were included, of whom 33 (10.4%) had malignant SBO. Out of the 33 patients with malignant SBO, 20 patients (60.6%) were treated with palliative intent although only 7 patients were seen by a palliative team during admission. Nutritional assessments were performed on 12 patients, and 11 of these patients received parenteral nutrition. 23 patients underwent surgery, with the most common surgical interventions being loop ileostomies (9 patients) and gastrointestinal bypasses (9 patients). 4 patients underwent right hemicolectomies, with a primary anastomosis formed and 1 patient had a right hemicolectomy with a terminal ileostomy. Median survival was 114 days, and no difference was seen in survival between patients treated with or without palliative intent. CONCLUSION: Malignant SBO is associated with significant risks of short-term complications and a poor prognosis. Consideration should be given to the early involvement of senior decision-makers upon patient admission is essential for optimal management and setting expectation for a realistic outcome.

Adult ileo-ileal intussusception caused by inflammatory fibroid polyp leading to small bowel obstruction: a case report with comprehensive literature review.

Ileo-ileal intussusception, an infrequent cause of small bowel obstruction in adults, can be initiated by inflammatory fibroid polyps. These are uncommon, benign submucosal lesions of the gastrointestinal tract. This case report explores an adult patient with inflammatory fibroid polyps-induced ileo-ileal intussusception.

Clinico-Epidemiological Analysis of Small Bowel Obstruction in Adults at a Tertiary Care Center in India.

BACKGROUND: Acute small bowel obstruction (SBO) is a common surgical emergency. The study aims to provide a comprehensive clinical-epidemiological description of SBO in adults at a tertiary care center in western India. METHODS: This hospital-based cross-sectional study was conducted from July 2020 to June 2022 and enrolled 88 SBO patients requiring surgical intervention. After adequately resuscitating the patients, various surgical procedures were performed based on the intraoperative conditions of the bowel. Patients were assessed postoperatively for the duration of their hospital stay, postoperative complications, and surgical recovery. RESULTS: There was a male preponderance (n=55), with a median age of 50 (18-90) years. Abdominal discomfort was the most frequent symptom, necessitating a hospital visit (97.9%, n= 86), followed by nausea (85.2%, n= 75), constipation (78.1%, n=69), and abdominal distension (51.1%, n=45). Ileal strictures (18.2%, n=16) were the most common etiology, followed by postoperative adhesions (14.8%, n=13) and bands (13.6%, n=12), of which 76.4% (n=9) had past surgical history. Resection and anastomosis were the most frequently performed surgical interventions in this study (36.4%, n=32), followed by stoma creation (27.3%, n=24) and adhesiolysis (17%, n=15). The postoperative 30-day mortality of 11.36% (n=10) was noted, which could be ascribed to the elderly population with comorbidity, postoperative complications, and who required extended stay in the critical care unit. CONCLUSION: Benign ileal stricture was the most common cause of acute SBO in the emergency. Prompt and timely diagnosis combined with a multidisciplinary approach and effective management can improve outcomes and reduce morbidity and mortality in adult patients with SBO.

Small Bowel Obstruction Secondary to Metastatic Urothelial Cell Carcinoma With Plasmacytoid Features: A Case Report.

Urothelial cell carcinoma (UCC) is a type of malignant cancer that affects thousands of people worldwide, especially those who smoke and have certain occupational exposures. Plasmacytoid urothelial carcinoma (PUC) is a rare histological variant of UCC that can present aggressively and insidiously. Small bowel obstruction secondary to malignancy is a rare presentation of UCC because the small bowel is a rare site of metastasis. We showcase a patient who presented with small bowel obstruction secondary to high-grade metastatic UCC with plasmacytoid features, exhibiting minimal urologic symptoms and no apparent risk factors. This case highlights the importance of high clinical suspicion for patients with possible malignancies that present with limited or unusual symptomatology and no risk factors. Further research into PUC to understand its symptoms and metastatic pattern is warranted to advance current early diagnostic criteria and further improve patient outcomes.

Managing abdominal cocoon syndrome complicated by intestinal necrosis and unexpected amelioration of depression after surgery: a case report.

BACKGROUND: Abdominal cocoon is a very uncommon yet dangerous cause of intestinal obstruction. CASE PRESENTATION: We present a case of a 62-year-old Asian male patient with a history of depression who exhibited an idiopathic abdominal cocoon complicated by necrosis. Upon laparotomy investigation, nearly the entire small intestine was enveloped in a thick membrane resembling a cocoon, and it was discovered that he lacked a greater omentum. The patient recovered well and was discharged on an oral diet on the 20th day following surgery. During the 3-month follow-up, the patient was asymptomatic, even gaining 10 kg in weight, and noted that his depression had improved. CONCLUSIONS: Small bowel obstruction presents with nonspecific symptoms, posing challenges in differential diagnosis. Contrast-enhanced computed tomography is recommended since it facilitates precise preoperative assessment, optimizing surgical planning and reducing postoperative complications. Remarkably, cessation of antidepressant medication post-surgery hints at a potential correlation between omental deficit, gut microbiota alterations, and depressive symptoms.

Determining the need for surgery in small bowel obstructions based on clinical, laboratory, and radiological parameters.

OBJECTIVE: Small bowel obstruction (SBO) is a common and important surgical emergency. Our aim in this study is to describe the clinical, laboratory, and computed tomography (CT) findings to facilitate the objective identification of SBO patients in need of operative treatment in this patient population. METHODS: This retrospective study included 340 patients hospitalized due to a preliminary diagnosis of ileus. Retrieved data of patients included age, gender, comorbidities, previous hospitalization due to ileus, surgical history, physical examination findings, complete blood count and biochemistry test results, and CT findings at admission. RESULTS: The study included 180 (52.9%) male and 160 (47.1%) female patients. Treatment was conservative in 216 patients and surgery in 124 patients. Of the patients included in the study, 36.4% needed surgery. Of the female patients, 38.90% received conservative treatment and 61.30% underwent surgery. Adhesions were the most common cause of obstruction in operated patients (43.50%). CONCLUSION: We have found that female gender, vomiting, guarding, rebound, C-reactive protein levels above 75 mg/L, increased bowel diameter, and a transition zone on CT images indicate a strong need for surgery, but a history of previous hospitalization for ileus may show that surgery may not be the best option.

OBJETIVO: Describir los hallazgos clínicos, de laboratorio y de tomografía computarizada (TC) para facilitar la identificación objetiva de los pacientes con obstrucción del intestino delgado que necesitan tratamiento quirúrgico. MÉTODO: Este estudio incluyó 340 pacientes. Los datos obtenidos fueron edad, sexo, comorbilidad, hospitalización previa debida a íleo, historia quirúrgica, hallazgos de la exploración física, hemograma completo y resultados de las pruebas bioquímicas, y hallazgos de la TC al ingreso. RESULTADOS: El estudio incluyó 180 (52.9%) varones y 160 (47.1%) mujeres. El tratamiento fue conservador en 216 pacientes y quirúrgico en 124 pacientes. De los pacientes incluidos en el estudio, el 36.4% necesitaron cirugía. De las mujeres, el 38.90% recibieron tratamiento conservador y el 61.30% se sometieron a cirugía. CONCLUSIONES: Encontramos que el sexo femenino, los vómitos, la guardia, el rebote, los niveles de proteína C reactiva superiores a 75 mg/l, el aumento del diámetro intestinal y una zona de transición en las imágenes de TC indican una fuerte necesidad de cirugía.

Prognostic value of CT findings for conservative treatment failure in adhesive small bowel obstruction.

PURPOSE: This study aimed to identify the radiological CT findings that are significantly correlated with the outcome of conservative management with oral water-soluble contrast medium in patients presenting with Adhesive Small Bowel Obstruction (ASBO) to the Emergency Room. METHODS: In this retrospective single-center study, we considered all consecutive patients admitted to the ER from February 2019 to February 2023 for ASBO with an available contrast-enhanced CT scan performed at diagnosis and treated with conservative management. The investigated CT findings were type and location of transition zone, ASBO degree, fat notch sign, beak sign, small bowel feces sign, presence of peritoneal free fluid and pneumatosis intestinalis. Radiological parameters were analyzed using univariable and multivariable logistic regression to test the significant association between the CT parameters and the target. RESULTS: Among the 106 included patients (median age 74.5 years), conservative treatment was effective in 59 (55.7%) and failed in 47 (44.3%), needing delayed surgery. In the failure group, there was a higher prevalence of patients who had previous ASBO episodes (p = 0.03), a greater proportion of females (p = 0.04) and a longer hospital stay (p < 0.001). At multivariable analysis, two CT findings were significantly correlated with failure of conservative treatment: fat notch sign (OR = 2.95; p = 0.04) and beak sign (OR = 3.42; p = 0.04). CONCLUSIONS: Two radiological signs correlate with failure of non-operative management in ASBO, suggesting their importance in surgical decision-making. Patients presenting with these signs are at higher risk of unsuccessful conservative treatment and may require undelayed surgical intervention.

Case report: Concurrent intussusception and bleeding marginal ulcer in a patient with gastric bypass.

INTRODUCTION: The source of abdominal pain in patients with a history of gastric bypass can be difficult to determine. Synchronous disease processes may ultimately be the cause of their symptoms. Among the etiologies for hematemesis and obstruction in this population are the diagnoses of marginal ulcer and internal hernia. Given the potential complications of bariatric surgery, it is important to maintain a broad differential diagnosis during the workup of these patients. PRESENTATION: A female with history of laparoscopic Roux-en-Y gastric bypass (RYGB) presented with abdominal pain and hematemesis. Intraoperative findings revealed intussusception of the jejunojejunostomy resulting in obstruction and ischemic bowel. Additionally, a perforated marginal ulcer of the Roux-limb was found to be present. This patient underwent esophagogastroduodenoscopy, bowel resection, jejunojejunostomy revision, and Graham patch repair. DISCUSSION: This case highlights a patient with history of RYGB presenting with obstruction and gastrointestinal bleeding. Although initially diagnosed with internal hernia and Mallory-Weiss hematemesis, surgical exploration revealed concurrent intussusception and marginal ulceration. While intussusception is a rare complication of bariatric surgery, it can occur secondary to mesenteric thinning and motility dysfunction from significant weight loss. It is imperative to maintain a broad differential diagnosis for the causes of obstruction and GI bleeding that include adhesive disease, abdominal wall hernia, internal hernia, intussusception, and marginal ulcers. CONCLUSION: Findings of obstruction or GI bleeding after bariatric surgery may represent a surgical emergency. While these symptoms may be attributed to a single diagnosis, clinicians must consider the presence of synchronous pathologies during the workup of patients.

Partial adhesive small bowel obstruction due to peritoneal tuberculosis HIV/AIDS patient: A case report.

INTRODUCTION: Diagnosing peritoneal tuberculosis is challenging due to unspecific clinical manifestations, particularly in immunocompromised patients with HIV/AIDS and tuberculosis infections. PRESENTATION OF CASE: An Indonesian man, 26-years-old, complained of mid-abdominal colic and constipation. The patient's present state exhibited symptoms of weakness and paleness, oral candidiasis, a bloated abdomen, palpable discomfort, and shifting dullness. The ascitic fluid analysis showed increased ADA (709 U/L), and detected Mycobacterium tuberculosis using GeneXpert MTB/RIF. Radiographic examination from abdominal x-ray and CT scan revealed a small bowel obstruction. He received intestinal decompression, pain control, intravenous fluid resuscitation, and correction of electrolyte imbalance for small bowel obstruction without any indication for surgical intervention. He also receive first-line ATD for 2 months during intensive phase and 4 months for continuous phase. After a period of 2 weeks following the ATD administration, the patient began taking ARV medication on a daily basis. He showed a good prognosis 6 months following. DISCUSSION: The diagnosis of peritoneal tuberculosis is challenging due to its unspecific manifestation and some cases are identified when complications such as small bowel obstruction appear. The ADA test and GenExpert MTB/RIF are useful instruments for promptly diagnosing tuberculosis. It is suggested to use ARV treatment in individuals with HIV/AIDS who have peritoneal tuberculosis, starting 2 weeks following ATD treatments. CONCLUSION: Peritoneal tuberculosis with small bowel obstruction and HIV/AIDS infection is a rare case in which early diagnosis and monitoring play an important role in successful treatment.

Adult Intestinal Malrotation With Congenital Transverse Meso-Colic Internal Hernia: An Infrequent Cause of Small Bowel Obstruction.

Adult intestinal malrotation along with congenital transverse-mesocolic internal hernia causing small bowel obstruction is extremely rare. Most of these patients don't have any obvious clinical symptoms. Only a few cases have been documented in the English literature. We present the unique case of a 43-year-old male without any prior surgical history who presented with nonspecific abdominal pain and was diagnosed with malrotation of the small intestine by computed tomography (CT) scan and underwent exploratory laparotomy found to have internal herniation through the transverse-mesocolon. The patient underwent an emergency laparotomy; a Ladd's procedure and repair of the hernial orifice were performed. This case highlights the association of adult intestinal malrotation with internal hernias and small bowel obstruction; it also explores the importance of timely diagnosis and adequate management of this condition.

Bouveret syndrome preceding classical gallstone ileus: a rare presentation of a cholecystoduodenal fistula.

Bouveret syndrome is the rarest variant of gallstone ileus characterized by the passage and impaction of a gallstone through a bilioenteric fistula leading to gastric outlet obstruction. The documented movement of an impacted gallstone in Bouveret syndrome through the gastrointestinal tract has not been previously discussed in the literature. A 64-year-old man presented with acute on chronic epigastric pain, fevers, and vomiting. Abdominal computed tomography established a diagnosis of Bouveret syndrome. A trial of endoscopic gallstone extraction was unsuccessful. Laparoscopic gastrotomy and stone removal were later attempted, however, intraoperatively it was noted that the stone had migrated and was now impacted in the jejunum causing a small bowel obstruction. The clinical picture was now that of gallstone ileus. Laparoscopic enterolithotomy was performed successfully. This article discusses the radiological, endoscopic, and intraoperative findings in this rare case of Bouveret syndrome that had evolved into classical gallstone ileus following stone migration.

Poorly Cohesive Carcinoma of the Nonampullary Small Bowel: A Rare Cause of Recurrent Small Bowel Obstruction.

Poorly cohesive carcinoma (PCC) is an uncommon neoplasm characterized by tumorous cells exhibiting a lack of adhesion. PCC has been reported rarely in the small intestine other than at the ampulla of Vater. We present a 40-year-old man with recurrent abdominal pain and small bowel obstruction. Imaging revealed an abnormal appearing distal small bowel, with only nonspecific mucosal changes discovered on antegrade and retrograde enteroscopy. On subsequent diagnostic laparoscopy, an ileal mass was found and resected with histopathology showing PCC with signet ring formation. This is an aggressive cancer with a worse prognosis than other small bowel adenocarcinomas.

Early Postoperative Small Bowel Obstruction after Colorectal Surgery: Incidence and Exploratory Analysis of Potential Risk Factors.

Background: Early postoperative small bowel obstruction (EPSBO) is a common complication following colorectal surgery, which can significantly impact patient outcomes. This study aimed to investigate the incidence of EPSBO and identify potential risk factors among patients who underwent colorectal surgery. Methods: A descriptive study was conducted on a cohort of 100 patients who underwent colorectal surgery at a tertiary center at SKIMS, Srinagar, Jammu & Kashmir, India. Descriptive, bivariate, and predictive screening analyses were performed to examine patient characteristics, assess association between different relevant variables and EPSBO, and identify significant predictors, respectively. Results: Our study included a total of 100 patients, with a mean age of 50.39 years. Postsurgery, 11% of the individuals in the cohort developed EPSBO. Early postoperative small bowel obstruction developed around 4.30 days after surgery, and radiographic data revealed dilated gut loops in 72.70% of EPSBO cases. Bivariate analysis revealed significant association between EPSBO and variables such as previously operated, medical comorbidities, smoking status, anemia, neoadjuvant chemoradiotherapy (NACRT), bowel preparation, operative procedure, surgery duration, and type of anastomosis (p < 0.05). History of previous bowel habits, previously operated, perioperative bowel preparation, and blood transfusion were identified as the most influential predictors of EPSBO in the predictive screening study. Conclusion: This study provides insights into the incidence of EPSBO and its potential risk factors for postcolorectal surgery among patients. The findings emphasize the need to take the patient's history of past bowel habits and other factors into account when determining the risk of EPSBO. Future studies should go deeper into these correlations and consider treatments to reduce the occurrence of EPSBO in this patient population.

Radiographic Features of a Strangulated Transomental Hernia.

This is a case report of an 82-year-old male who presented with intractable and diffuse abdominal pain and had a computed tomography (CT) abdomen showing a closed loop obstruction in the right hemiabdomen with anteromedial displacement of the cecum and ascending colon. Exploratory laparotomy revealed a gangrenous segment of the ileum strangulated by a transomental hernia in the right lower quadrant. The nonviable bowel was resected, and the healthy bowel segments were anastomosed. It is important to correlate the clinical signs of bowel obstruction with radiographic findings of internal hernia to expedite surgical intervention and prevent complications of bowel ischemia.

Optimal bowel diameter thresholds for diagnosing small bowel obstruction and surgical intervention with point-of-care ultrasound.

OBJECTIVES: A bowel diameter threshold of ≥2.5 cm, originally derived from the research using computed tomography, is frequently used for diagnosing small bowel obstruction (SBO) with point-of-care ultrasound (POCUS). We sought to determine the optimal bowel diameter threshold for diagnosing SBO using POCUS and its accuracy in predicting surgical intervention. METHODS: We conducted a secondary analysis using individual patient-level data from a previous systematic review on POCUS for SBO diagnosis across five academic EDs. Patient data were collected, including imaging results, surgical findings, and final diagnosis. The measured diameter of the small bowel using POCUS was recorded. ROC area under the receiver operating characteristic curves (AUC) were constructed to determine the optimal threshold for bowel diameter in predicting SBO diagnosis and surgical intervention. Subgroup analyses were performed based on sex and age. RESULTS: A total of 403 patients had individual patient-level data available, with 367 patients included in the final analysis. The most accurate bowel diameter overall for predicting SBO was 2.75 cm (AUC = 0.76, 95% CI 0.71-0.81). A bowel diameter of ≤1.7 cm had 100% sensitivity with no miss rate, while a bowel diameter of ≥4 cm had 90.7% specificity in confirming SBO. Patients under 65 had an optimal threshold of 2.75 cm versus 2.95 cm in patients over 65. Females had an optimal threshold of 2.75 cm, while males had a value of 2.95 cm. There was no significant correlation between bowel diameter thresholds and surgical intervention. CONCLUSION: A bowel diameter threshold of 2.75 cm on POCUS is more discriminative diagnostic accuracy for diagnosing SBO. Patients' age and sex may impact diagnostic accuracy, suggesting that tailored approaches may be needed.

Sclerosing Mesenteritis Presenting With Small Bowel Obstruction in a Patient With Systemic Lupus Erythematosus: A Case Report.

Sclerosing mesenteritis (SM) is a rare inflammatory disorder characterized by chronic inflammation and fibrosis of the mesenteric adipose tissue. While SM can manifest with various gastrointestinal symptoms, its association with small bowel obstruction (SBO) is infrequent. We present a case of a 78-year-old male with a history of systemic lupus erythematosus (SLE) who presented with acute abdominal pain and distention. The patient had multiple admissions with the same symptoms. A CT scan showed swirling of the proximal central mesentery, small bowel malrotation with volvulus, and high-grade mechanical obstruction of the proximal jejunum. The patient underwent exploratory laparotomy, with findings significant for multiple inflammatory nodules in the mesentery. These were causing adhesions between the bowel and mesentery, resulting in a volvulus of the bowel. One segment was resected, and subsequent histopathological examination revealed subserosal fibrosis and chronic inflammation. The clinical scenario was consistent with a diagnosis of SM. This case highlights the challenges of diagnosing and managing SBO in the presence of SM and SLE. Further research is needed to understand the underlying pathophysiological mechanisms and improve management techniques for this rare clinical condition.

The role of computed tomography in acute bowel obstruction due to a supravesical hernia: a case report from Nepal.

Introduction and importance: Supravesical hernias are rare internal hernias but potential cause of small-bowel obstruction. The clinical features are often non-specific, preoperative diagnosis is very difficult and is often diagnosed intraoperatively. The exact pathogenesis is unclear with the major risk factors of prematurity, a positive family history, male sex, smoking habits leading to decreased collagen production, advancing age, and conditions characterized by defective collagen synthesis. Case presentation: The authors are reporting a case of small-bowel obstruction secondary to a supravesical hernia, in a 78-year-old male presented with central abdominal pain, vomiting and obstipation. Ultrasonography of the abdomen and pelvis identified a marked dilation of the small-bowel loop with multiple loops of dilated jejunum and ileum in contrast-enhanced computed tomography (CT) scan of the abdomen and pelvis with lead point from the terminal ileum. Exploratory laparotomy was done with the diagnosis of left posterior a left posterior superior vesical hernia with small-bowel obstruction. Clinical discussion: The case focuses supravesical hernia as a rare yet life-threatening etiology of small-bowel obstruction, emphasizing the importance of clinical suspicion when patients present with signs and symptoms of bowel obstruction. While diagnosis often occurs intraoperatively, the utilization of CT scans in emergency settings can provide valuable insights into the location, potential causes, and condition of the herniated bowel sac. The case highlights the pivotal role of CT scans in diagnosis and emphasizes the need for multidisciplinary cooperation among clinicians, radiologists, and surgeons. Conclusion: Early intervention ensures better outcomes and prevents irreversible bowel damage, underscoring the importance of a comprehensive approach to patient care.

Successful Multidisciplinary Treatment of Small Bowel Obstruction With an Ileal Stricture Resulting in Bowel Perforation in the Setting of Multidrug-Resistant Gastrointestinal Tuberculosis: A Case Report.

We present the case of a male in his 40s who recently emigrated from Russia and was actively undergoing treatment for multidrug-resistant (MDR) pulmonary tuberculosis (TB) with the BPaL-M (bedaquiline, pretomanid, linezolid, moxifloxacin, and pyridoxine) regimen who presented to the emergency department (ED) with abdominal pain, vomiting, and no bowel movements. A computed tomography (CT) scan of the abdomen and pelvis revealed a small bowel obstruction (SBO) from ileal stricture consistent with gastrointestinal (GI) TB. He did not require an emergent surgical intervention and was managed conservatively via bowel rest and initiation of total parenteral nutrition (TPN). An oral BPaL-M regimen was held and an intravenous (IV) regimen consisting of linezolid, moxifloxacin, meropenem, and ampicillin/sulbactam was started per infectious disease (ID) recommendations. He improved clinically over the next several days and was started on a diet that was initially well tolerated. Shortly after transitioning to a regular diet, he developed severe abdominal pain. A CT scan of the abdomen and pelvis revealed pneumoperitoneum and he was taken emergently to the operating room (OR) for exploratory laparotomy (ex-lap). A perforation was found in the terminal ileum and he underwent a right hemicolectomy. He returned to the OR two days later for ileocolic anastomosis and fascial closure. A diet was initiated once again which was tolerated well. He was then transitioned back to his oral BPaL-M regimen which was also tolerated well. He was discharged home on an oral diet after a 23-day hospital course with follow-up appointments with acute care surgery (ACS) and ID.
